What happen when she/he meets him/her? Do you wonder why? 的

How cells communicate each other in insects? Endocrine system-hormone:ultimately communicate with every cell by traveling through the circulatory system. Take minutes or hours to reach the target cells.Slow!l! Nervous system-electrical signals coordinating cellular events. Take milliseconds to reach a distance target.Rapid!!!
